Hey, I'm
Ashiqul
Islam Ayon.
I build backends: APIs, databases, and the servers they run on, plus the interfaces that sit on top. Some of it for a startup, the rest under my own name.

learning
Getting properly comfortable with Postgres query plans instead of guessing at indexes.
what I reach for
so far
about
I work on the half of the product nobody sees.
Schemas, API boundaries, background jobs, and the unglamorous infrastructure decisions that determine whether a thing still works at 3am. That's most of my job, and I genuinely like it.
I got here the slow way, building things that broke and then having to work out why. That's also how I ended up mentoring: the moment a deploy stops being scary for someone is a good moment to be present for.
These days I split my time between backend work at a startup and a handful of products I run myself, which is the best way I've found to keep learning things I wouldn't otherwise pick.
- 01
I write backends first and interfaces second, and I think it shows in the interfaces.
- 02
I default to boring technology. Postgres and a single server solve more than they get credit for.
- 03
Most of what I know about production came from breaking it at 2am and having to fix it.
- 04
I teach because explaining something is how I find out whether I actually understood it.
where I've worked
Three jobs, one of them my own.
- Jul 2025 to PresentFull-time · Remote
Backend Developer
Join Venture AI
Building the backend services behind the core platform and everything user-facing.
Own the APIs for auth, user management, and most of the business logic.
Run the production servers: deploys, reverse proxy, SSL, the whole unglamorous stack.
Moved the slow work into background jobs, which fixed most of our latency complaints.
- May 2025 to Jun 2025Full-time · Remote
Software Engineer
EdCluster
Shipped core backend features on an early-stage product, at early-stage speed.
Helped shape the backend structure so it wouldn't need rewriting in six months.
Testing and debugging against deadlines that did not move.
- 2023 to PresentIndependent · Bangladesh
Online Programming Mentor
Self-employed
Mentoring developers in backend and full-stack work, one-on-one and in small groups.
Built learning paths through backend architecture, API and database design, and deployment.
Reviewing code and giving the kind of feedback I wish I'd had earlier.
Mostly helping people get from following tutorials to shipping something real.
things I made
Products I run myself.
All live, all mine to maintain, which is the part that teaches you the most.
Blink Deal
A coupon site that only lists codes I can verify still work. Most of the engineering went into checking them, not displaying them.
Tool Blink
Converters and compressors for images, documents and developer data. No signups, no installs, no upload limits I have to apologise for.
Travenor
Destination guides and cultural deep-dives on Bangladesh, written as a local rather than translated from a guidebook.

I talk about this stuff out loud too.
I couldn't load the feed just now, but everything's on the channel.
Open the channelSay hello.
I usually reply.
Work, a question about a deploy that's misbehaving, or something you're building and want a second opinion on. All fine.
